New line of remote particle counters
Adams Instruments announces the introduction of its new line of remote particle counters. The R-Series Remote Particle Counter can be integrated using either Ethernet (TCP/IP) or Serial Modbus RTU communications, and it can be powered over its Ethernet connection (Power-Over-Ethernet compliant with IEEE 802.3af) to simplify installation, or via a local power supply. The R-Series can be configured locally with a PC or via a Web browser and no dip switches or jumper settings are required for set-up. The instrument reports up to four particle sizes simultaneously, as well as other key information for Total Monitoring System Management™ such as laser current, laser accumulated on-time, background light level, date of last calibration, serial number and date of manufacture for easy warranty management. Calibration is performed digitally, allowing for consistency when managing a large number of instruments. With the optional Temp/RH sensor, users can avoid cabling and powering a separate sensor into a monitoring or building automation system. Each R-Series Remote Particle Counter also includes an alarm output, which allows users to alarm locally from the particle counter. Additional features include: compliance with JIS Standards; storage of up to 500 sample records; optional flow alarm; RoHS compliance; low outgassing and ionics; stainless-steel enclosure; flexible mounting options; use of external vacuum source; and a three-year limited warranty.

The Met One 3400 Series Portable Airborne Particle Counter from Hach Ultra features faster sampling, ease of use and reduced technician time. Available in two flow rates, 50 L/min or 28.3 L/min, and a sensitivity range of 0.3 to 25 microns, the 3400 offers flexibility for QA/QC and technical managers to verify critical processes and environments, including cleanrooms. The 3400 Series also contains Long Life Laser™ technology, extending the instrument’s average laser life to more than 10 years. Lightweight and compact, the 3400 features handles for easy lifting and it can relocate to various sampling sites for data collection throughout a facility. Both horizontal and vertical orientations of the instrument are possible, and dual hot-swappable batteries minimize downtime. The instrument’s stainless-steel construction and unobstructed surface facilitate quick and frequent wipe-downs. With PortAll Version 2 Life Sciences Version, the 3400 provides the necessary regulatory documentation for 21CFR Part 11 compliance.

Air sampler calibration

According to Good Laboratory Practices and Good Manufacturing Practices, the functionality of a microbiological air sampler should be evaluated regularly to ensure that it’s working according to the manufacturer’s specifications. The new Pyramid Flow Check from international pbi is an easy-to-use, battery-operated system for calibrating an air sampler. The instrument comprises two separate units: a fan and a flow meter. The Pyramid is positioned on the top of the sampler and the propeller produces an electric field that is proportional to the speed of the air. The system measures the electromagnetic field and calculates the airflow, which is displayed in liters per minute or cubic feet per minute. The unit is available with IQ/OQ documentation.

Particle instrument trade-in program

TSI offers a particle instrument trade-in program, available through the end of 2007. For select instruments, TSI offers a trade-in discount of up to 15 percent, credited toward the purchase of a new instrument, when you tender an equivalent older model in trade. The program is intended to replace older instruments that no longer represent the latest technology and have become increasingly expensive to maintain or impossible to repair due to the age of the instrument’s components. Qualifying instruments include: CPC Models 3020, 3022, 3022A, 3025, 3025A, 3760, 3760A, 3762, 3010, 7610 and 7620; APS Models 3300, 3310 and 3310A; Electrostatic Classifier Models 3071 and 3071A. These older models do not need to be operational to qualify for the trade-in.
